RECTANGULAR GAS-PRODUCER.

Specification of Letters Patent.

Patented Sept. 23, 1913.

Application filed April 9, 1910. Serial No. 554,541.

To all whom it may concern:

Be it known that I, REGINALD B. INIILDON, a citizen of the United States, and a resident of /Vilkinsburg, in the county of Allegheny and State of Pennsylvania, have made a new and useful Invention in Rectangular Gas-Producers, of which the following is a specification.

This invention relates to gas producers and particularly to a double zone gas producer in which there is a vaporizer at the intersection of the upper and lower zones.

One of the objects of my invention is to produce an inexpensive but practicable gas producer which will efficiently perform the work for which it is intended.

A further object is to provide means whereby two vaporizing chambers may be supported by opposing walls of the lower zone and in turn support opposite walls of the upper zone or protect the bottom of the walls of the upper zone.

Other objects and advantages of this in vention will appear as the nature of the invention is better understood, it being obvious that changes in form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.

In the drawings, Figure 1 is a vertical, longitudinal, sectional view through a producer constructed in accordance with my invention; Fig. 2 is a plan view of the same; Fig. 3 is a fragmentary perspective View showing the relation of the vaporizer to the walls of the upper and lower zones, and Fig. 1 is a fragmentary view of the producer showing one manner of securing the ends of the Vaporizers to the walls of the lower zone.

Referring now to the drawings by nu morals of reference, 1 designates the lower zone of a gas producer which is polygonal in cross section. The producer here shown is illustrated as being rectangular and one advantage of this is that the Vaporizers, of which there may be a plurality, may be terminally secured to the walls of the lower zone and protect the bottom of the walls of the upper zone from contact with clinkers as well as support portions of the walls of the upper zone. Another advantage is that poke holes can be so arranged in the side walls, that the sides may be easily cleaned.

I am aware that it has been proposed to provide a vaporizer at the top of the walls of the lower zone of a double zone producer but I am not aware that it has been contemplated to provide an elongated vaporizer which may be terminally supported by the producer, nor am I aware that it has been proposed to carry separate Vaporizers in a producer which is polygonal in cross section. The form of producer illustrated includes two opposite walls, two for the lower zone, two for the upper zone, and two end walls 3. Running along the upper edges of the walls 2 are two Vaporizers a, one for each wall. These Vaporizers comprise hollow bodies which are a iiproxiinately Z shape in crosssection, communicating with the gas chamber 5, provided with an off-take 6. The lower projecting portion 7 is in line with a wall 8 of the upper zone 9 and in some instances the portion 7 will support a wall 8, but if the wall 8 is supported by an arch bar (as it may be under certain conditions) the portion 7 will protect it. The ends of the vaporizer are provided with flanges 10 which may be fastened to the walls 3 by rivets or other fastening devices 11 and the exterior of both zones may be covered with suitable covering material as indicated at 12 for the lower zone and 13 for the upper zone. The Vaporizers are each provided with suitable poke holes 1 1, and blow-off connections 15 are provided. It will be observed that a gas producer constructed in accordance with my invention will be extremely inexpensive and yet efficient in its operation. It will only be necessary to form four walls for the lower zone and support two elongated Vaporizers 1 by opposite walls, which I will term end walls 3, and if desired, the Vaporizers 4 may in turn support opposite walls 8 of the upper zone. The vaporizer may be made of sheet metal, cast or otherwise formed.

Poke holes 17 formed in the walls of the lower zone at the intersection on the plane of the walls and the exterior of the producer permit the introduction of poke bars to clear the inner walls from clinker-s.

Having now described my invention, what I claim is:

1. A gas-producer having a lower zone rectangular in cross-section, two removable Vaporizers on opposite sides of the lower zone and having flanges at their respective ends whereby said Vaporizers are secured to the walls of the lowerzone, and an upper Zone of less diameter than the lower Zone and having said walls supported by the Vaporizers.

2. In a gas-producer polygonal in cross section, oppositely located hollow bodies 7 comprising Vaporizers supported at their respective ends to opposite lower Walls of the producer, the lower edges of said vapori zers resting on the upper edges of the side walls of the producer and upper walls for the producer supported upon the Vaporizers.

In testimony whereof, I have hereunto 15 subscribed my name this 7th day of April, 1910.
